T all whom 'it 'ma/y concern:

Be it known that L Fnnninnok O. H'iL- rinnu, a citizen of the United States, residing at llion, in the county ot Herkimer and State of Newl York, have invented certain new and useful vlmprovenientl in lYater- 'horizontal sectional view on Closets, ot which the following is a specilifation, reference heilig had therein to the accompanying drawing.

My invention relates to an improved vvater closet, and .l declare that the following is a full, clear, concise and exact description thereot, auttieient to enable one skilled in the-art.to make and use the same, reterenee heilig had to the accompanving drawing.-A in which like letters and numerals reter to like parts throughout.

Among the particular i'eaturee oit m v invention is that it comprises a minimum inunber ot' parts, the several members heilig int-egral so t'ar as possible and so constructed as to be assembled without the neceasity ot Yashers, the said parts being largely or altogether Ot cast membera so that l avoid all machine work on the device.

Another feature is that there can be no leakage save thatoccasioned lby overtlow.

Further detailhl oi the invention will appear from the following specifications and the drawings. A ln the drawingl Figure l is a sectional view on the medial i'ront to rear line; Fig. 2 is a front view ot the upper part or tank portion, certain parts being broken awa)7 to show the interim' members, and Fig. El is a the line .c-.c oi lfig. 1.

le'terriirg to the drawings in detail. the device comprises water-tank and howl portion ll which can he ot any Suitable st vle. The portion designated by the general retereuce as A comprises a ank, which l prefer to make ot' porcelain or other Suitable inaterial. having the Valls 1 and 2 together with end walla--not shown. The front wall 2 hae a bore from bottoni to top, the interior portion of the wall not extending however to the top ot the other portions, the said bore being `indicated by 3 and provided for vertical pla)v ot' the operating rod -t which has a handle 5. This bore also serves as an overflow` its lower outlet opening vinto a reabove the water level. so that through these holes l can innert Screws or other fastening device and thereby fasten the tank to the wall. ln the interior of the tank A is 'formed a Siphon with 'long arm 7 having its lower end enlarged, as hereat'ter pointed out, and the short ar-m S. tl represente .1 .-ihort pipe connected to the IVahort arm ot the Siphon adjacent itel top and extending nearly vto the bottom, the purpose ot` which is to admit air after the operation ot the closet. The tank Aand the Siphon members, as above described, are formed with. a rim at the lower portion to rest upon the .top vof basin or bowl portion ll, theriin ot' the tank portion overhanging the rim ot the bowl portion, as clearlyY seen in Fig. l. y

'l`he bowl portion lil-is shown as integral. conaisting oi the front portion which is of the usual cmmnm'cial itorin and of the general character, as indicated in Fig. l, and the rear upward extending portion designated as l0 terminating in a itat edge `tor the support ot the tank members with'the s-tiphon, Supported in' the upright portion 1t), as b v a bracket 1l, an annular cup l2 adapted to hold water and into which the enlarged end 13 ot' the eiphon extendfsl reaching aubatantiallv to the bottom of the cup. Tvithin the annular interior space ot the, cup, ahown :if-H14, ie a cylindrical valve inemher l5 which consists ot a pipe whicli may be made ot metal, but which I prefer to inake of porcelain or other like ware. The upper end ot' this valve member is inverted will: walls lt ot a Yreater diameter returning on the wallbl ol' the pipe in inverted U- toria. the return end otl the pipe resting also in the cup` the edge ot the inverted end extending auhatantially to the bottom. This valve member ia open at each end and at the lower end is attached'th'e operating rod Ll, no that as* the rod is lifted it. raises the valve partially out otl the Cup. The return end` It. ot the valve member is of Such bulk that when the valve is at rest it displaces water in the cup falls to a level whereby the air which is in the longer end of the Siphon can escape between the inner wall of the end 1G and th'e outer wall ofthe valve member 15 and thence through aperture 3, or elsetion l() extends pipe 2Q which connects to the jet orifice 25% of the bowl.

Yormall)7 the 'ater in the tank is at the level Shown in Fig. l, the water supply being controlled by a suitable ball-cock, and

enough water so that when it is elevated the,

where. From the bottoni oi the uprightI porthe air is compressed in the long arm of the siphon and the upper end of the short larm. lber is also raised and the ends of the upset When rod l is lifted the valve memwalls 1G are lifted to a point just above the lowered level of the water in the cup. The" air then escapes, as pointed out, and the siphon acts undernatural laws, whereby. the water in the tank passesv up through the short arm of the Siphon, down through the long arm, through the valve member 15, lilling the upright portion l() ot the seat or bowl member whence it flows through pipe 22 into the jet 23, thence outward through the flush 20.

It also rises to discharge through the rim outlets 2l. The handle being dropped, the valve member returns to its seat. When the water has been exhausted its level is below the lower -end of the pipe 9 and the air rushes into the Siphon through that pipe, lling the vacuum caused by the discharge andthe water rising in the tank compresses the air in the siphon when the apparatus is in condition for repeated operation. The annular cup 12 and the bowl are amply refilled after each operation by the water left standing in upright portion 10. This water flows into the bowl through the pipe 22 and through thev 'member of the siphon'extending downwardly in an enlarged portion, a bowl portion having an upward e.\'tending chamber, the tank being adapted to be .supported thereon, a cup-seal mounted in the said chamber to receive the extended arm of the Siphon and a vertically movable valve adapted to be sealed by the cup-seal and to -cause the flush of the be opened to break the seal and effect dis,

into said seal, and of an l enlarged bulk whereby to quicken the action of the siphon on lifting the valve,I the said Amembers -eooperatingv on the lifting of vthe valve 'to device, substantially as shown. f

valve having a return portion extending 4. A device of the character described,

having a bowl portion with an upward eX- tended chamber, a tank member positioned for the discharge therefrom into the said chamber and having a Siphon with one member extended into said chamber, and a valve adapted to control the operationof the siphon comprising a Water-cup, the said cup being mounted to be maintained by the discharge of the Siphon in'condition for operation of the valve, substantially as shown.

5. In a device of the character described, a siphon having one member extending downwardly in an open-end portion,` the said Siphon also comprising, a cup-seal receiving the said open-end portion and a vertieallyY movable valve'having an end extend' .ing into the cup-seal and adapted upon its upward movement to operate the Siphon, substantially as described.k

(3. siphon comprising a. fixedly mounted cup-seal, a depending member extending in an open end into the seal, a vertically movable valve member depending into the cup-seal and adapted by the raising ot the .same to break the seal of the'siphon, substantially as described. ln testimony whereof l allix my sigiiature in presence o'l two witnesses.
